We look at the division of 91260805 by 810 
We're looking to find how many times 810 goes into 91260805.

Advancing to step 1:
810 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 810

Moving on to step 2:
The number 810 fits into 91 0 times, leaving a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Take the next digit (2) from the dividend and append it to 91, then repeat: 912 / 810

Advancing to step 3:
912 divided by 810 is 1 with a remainder of 102.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 810 away from 912, we end up with 102.
Grab the next digit (6) from the dividend, add it to 102, then carry on: 1026 / 810

Advancing to step 4:
The number 810 fits into 1026 1 times, leaving a remainder of 216.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 810 from 1026 and we're left with 216.
Take the next digit (0) from the dividend and append it to 216, then repeat: 2160 / 810

Step 5:
810 can be fit into 2160 2 times, resulting in a remainder of 540.
Write down 2 as next digit of the result. 
Result so far: 112.0
If we take 1620 away from 2160, we end up with 540.
Fetch the next digit (8) from the dividend, attach it to 540 and continue: 5408 / 810

Going ahead to step 6:
When dividing 5408 by 810, we get 6 with a remainder of 548.
The number 6 becomes the next digit in our result. 
Result so far: 1126.0
The remainder is 548 after subtracting 4860 from 5408.
Take the next digit (0) from the dividend and append it to 548, then repeat: 5480 / 810

Going ahead to step 7:
5480 divided by 810 is 6 with a remainder of 620.
Use 6 as the next digit of our solution. 
Result so far: 11266.0
The remainder is 620 after subtracting 4860 from 5480.
Include the next digit (5) from the dividend after 620, then repeat: 6205 / 810

Advancing to step 8:
If we divide 6205 by 810, we get 7 and a remainder of 535.
Use 7 as the next digit of our solution. 
Result so far: 112667.0
If we take 5670 away from 6205, we end up with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Step 9:
810 can be fit into 5350 6 times, resulting in a remainder of 490.
Use 6 as the next digit of our solution. 
Result so far: 112667.6
If we take 4860 away from 5350, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Going ahead to step 10:
810 goes into 4900 6 times with a remainder of 40.
The next digit of our result is 6. 
Result so far: 112667.66
If we subtract 4860 from 4900, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 112667.66 and a remainder of 0.04.
